Bone weight,meat yield estimates and cod (Gadus morhua): A preliminary study of the weight method

Past approaches to the Weight Method (use of the weight of excavated bone assemblages to evaluate the relative potential meat yield of the animals from which they came) are critically reviewed. They do not account for both inter-taxon and intra-taxon variability in the relationship between bone weight and total body or soft tissue weight. Critics of the Weight Method have assumed that these problems are insurmountable. It is argued here that they can be overcome practically. Solutions lie in the integration of classic Weight Method approaches, which assume a consistent ratio of bone weight to body weight between different taxonomic and size groups, with the understanding of animal scaling provided by studies of skeletal mass allometry. Allometric equations derived from original data (regarding cod, Gadus morhua) and available from published sources (regarding mammals and birds) are used to illustrate this argument. Three practical approaches to the Weight Method are suggested and briefly explored, using bone weight data from Earls' Bu, a Norse site in Orkney, Scotland, as a case study.     

Coupling lead isotope analysis and petrography to characterize fabrics of storage and trade containers from Hala Sultan Tekke (Cyprus)*

Lead isotopes, thin‐ and sherd‐section analyses are coupled on pottery‐vessel fragments excavated from the Late Bronze Age site of Hala Sultan Tekke (south‐east Cyprus) and representing fabrics used for the production of storage and trade containers. The fabrics of the sherds are first described according to general macroscopic observations. Based on the different fabrics identified, a petrographic analysis is carried out on thin sections and compared to lead isotope results on the same samples. This study shows that a specific fabric corresponds to a specific lead isotopic composition and proposes different sources for the various groups of associated sherds/fabrics. It also demonstrates the compatibility and complementarity of petrography and lead isotopes within pottery provenance study.     

Losing it in Hawai‘i: Weight Watchers and the paradoxical nature of weight gain and loss

In Hawai‘i, bodies may be big, successful, widely accepted, and revered by their public, yet some subjects may simultaneously be seeking a thinner body even with what appears to be ‘fat acceptance’ by many state residents. This article analyses weight and weight loss narratives of two prominent public and nonwhite men, Israel Kamakawiwo‘ole and Sam Choy. We connect these narratives to Weight Watchers International discourses of slimming as these apply to ‘nonwhite’ subjects in Hawai‘i. We suggest that Weight Watchers normalizes thinness through discourses of whiteness inherent in particular foods. Hawai‘i's regional cuisine known as ‘Local Food’ is framed as ‘exotic,’ which is distinct from what the organization proposes is ‘good’ food that produces ‘healthy’ bodies. Weight Watchers narrates slim bodies and health while normalizing ‘white’ cuisine and the bodies who consume it thereby excluding Local brown bodies in Hawai‘i.     

Remodelling the past – Archaeometrological analysis applied on Birka weight material using a 3D scanner & Computer-Aided Design

Archaeometrological analysis has traditionally involved reconstructing the originally intended mass of a weight by hand; measuring with a calliper or a profile microscope, as well as using the artefact’s displacement in water for factors such as volume and density. Ideally, corrosion was to be left intact, which is inconsistent with the goals of the conservationist. In all, the process was time consuming and may in some cases even have accelerated the deterioration of the artefacts.     

Archaeological Quantification of Pottery: The Rims Count Adjusted using the Modulus of Rupture (MR)

Archaeological quantification is a recurrent issue in research about pottery, its typologies and its distribution. We accept the validity of other methods of quantification—sherd count, minimum number of individuals (MNI) or sherd weight—but the methodology that we have proposed for quantification of assemblages of archaeological contexts is the rims count, which has to be transformed into coefficients of reference through a correction using the modulus of rupture (MR). Such correctors are obtained through measuring the percentage of preserved rim of a significant number of sherds of each type and establishing the average of that percentage. This quantification method is easily applicable to all pottery types and it is also statistically reliable. Besides, it can be used in any study in which the gross number of rims is published. Finally, in the case of ceramic transport containers, a second correction can be applied by multiplying the corrected coefficient (number of rims × MR) by its average capacity (AC), another corrector that will allow us to gather statistics according to the litres of transported product. We believe that the rims count (the easiest part to classify) is a fast, relatively easy and very reliable method that needs to be corrected using the MR.     

秦汉度量衡制度的考古学研究

秦汉时期是中国度量衡发展史上的重要时期,自商鞅变法实施"平斗桶、权衡、丈尺"的政策以来,秦汉帝国在全国范围内大力推行度量衡的统一。本文依据出土和传世的度量衡实物对秦汉时期的度量衡制度作了探讨,并概述其特点,如"以度审容"、进位关系、测量基准等等,由此可以看出秦汉时期奠定了中国古代度量衡制度发展的基础。     

The Lower Palaeolithic on the northern plateau of the Iberian Peninsula (Sierra de Atapuerca,Ambrona and La Maya I): a technological analysis of the cutting edge and weight of artefacts. Developing an hypothetical model

This article analyses the relationship between the weight and cutting edge of lithic artefacts from the main Lower Palaeolithic sites on the northern plateau (Meseta) of the Iberian Peninsula. The weight and cutting edge of a tool determine its cutting ability and the amount of force it is capable of, making them extremely important aspects of study to further our understanding of the potential capacity for human intervention in the environment. However, the analysis of these features has not received much attention in the ongoing debate on the Palaeolithic era in Europe. This study argues that the quantitative and qualitative technological analysis of these two aspects is of fundamental importance in determining the potential of lithic assemblages.
